L'angle de coupe de l'exercice de torsion ordinaire standard est de 118, l'angle de biseau du bord de croix est de 40 ° ~ 60 ° et l'angle arrière est de 8 ° ~ 20 °. Pour des raisons structurelles, l'angle de râteau est grand au bord extérieur et diminue progressivement au milieu, et le bord transversal est un angle de râteau négatif (jusqu'à environ -55 °), qui agit comme extrusion lors du forage. Afin d'améliorer les performances de coupe de la perceuse de torsion, la partie de coupe peut être broyée en différentes formes en fonction des propriétés des matériaux transformés (tels que la perceuse de groupe).
